The Company
Environment Technology imports, distributes and supports AES (Advanced Enviro-Septic™) products developed in New Hampshire, USA, by Presby Environmental Inc. We provide information and advice on this quality, cost-effective option for domestic, commercial and remote on-site wastewater disposal.

Our team has a background of 30+ years in civil engineering specialising in drainage and general contracting, which in recent years has more focused on installation of on-site wastewater systems. Our search for effective wastewater treatment systems that could be designed and installed with confidence in the long-term outcome for our clients, resulted in the introduction of the AES system to New Zealand.

We provide information to septic system designers and installers, including full support for their first projects and ongoing peer review of designs.  As more designers and installers become AES Certified we facilitate connections between home and business owners and these professionals.

In 2010 we formed an associated design company, Wastewater Design Ltd, specialising in detailed site assessment and design information for building consents and property records.
